There are three pieces of this massage chair. One piece is received on the nineteenth day after the order is placed. There is no information on the other two pieces on the Internet. During this period, we communicated with the customer service and asked us to wait. After another two weeks, we received the remaining two shipments. Fortunately, every part of the chair can work, and the exterior is slightly damaged. The airbag design of the arm is unreasonable, and the distance is too far to be basically unusable.
